[0002] An asphalt heating tank is a specialized device for storing, heating, and blending asphalt. It heats the asphalt to a suitable temperature, making it easier to store, transport, and apply during construction. Simultaneously, the asphalt heating tank also functions as a blending tank, ensuring that the quality and performance of the asphalt meet construction requirements.

[0003] A search revealed Chinese Patent Publication No. CN217287962U, which discloses a heated mixing tank for asphalt production, relating to the field of asphalt processing equipment. Addressing the problem that existing mixing tanks lack heating capabilities, causing asphalt to solidify at low temperatures during mixing, the following solution is proposed: The tank includes a support base and a tank body. Support feet are fixedly installed at the four corners of the bottom of the support base, and the tank body is fixedly installed at the top of the support base. The bottom of the tank body penetrates the support base, and a funnel is fixedly installed at one end of the tank body through the support base. A heating layer is sleeved on the side wall of the tank body.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: when asphalt raw materials are in contact with the mixing tank for a long time, they will adhere to the inner wall of the mixing tank. As a result, it is difficult to remove the asphalt raw materials adhering to the inner wall of the mixing tank during the feeding process, leading to the waste of asphalt raw materials.

[0005] Therefore, in response to the above problems, the applicant provides a heated mixing tank for asphalt production. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, this application provides a heated mixing tank for asphalt production.

[0007] This application provides a heated mixing tank for asphalt production, which adopts the following technical solution:

[0008] A heated mixing tank for asphalt production includes a fixed ring, a motor A positioning block, and a bearing. The motor A positioning block is provided with a rotating mechanism, which includes a driven gear, a driving gear, and a motor A. The rotating end of the motor A is fixedly connected to the driving gear, the driving gear meshes with the driven gear, and the driven gear is fixedly connected to the outer wall of the mixing tank.

[0009] The bearing is provided with a wall scraping mechanism, which includes a slot block, an insert block and a "C"-shaped wall scraping plate. The insert block is inserted into the slot block, and a "C"-shaped wall scraping plate is fixedly connected to one end of the insert block.

[0013] Optionally, a bearing is rotatably connected to the outer circumference of the stirring rod, and a fixing rod is fixedly connected to the outer ring of the bearing and fixedly connected to the bottom end of the motor B.

[0014] Optionally, a slot block is fixedly connected to the outer circumference of the bearing, a threaded hole A is passed through the slot block, an insert is inserted into the slot block, a threaded hole B is opened on the insert, and nuts are threadedly connected to the threaded hole A and the threaded hole B.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses a heated mixing tank for asphalt production.

[0028] like Figure 1-6 As shown, a heating and mixing tank for asphalt production includes a fixed ring 2, a motor A positioning block 7, and a bearing 13. A rotating mechanism is provided on the motor A positioning block 7. The rotating mechanism includes a driven gear 4, a driving gear 5, and a motor A6. The rotating end of the motor A6 is fixedly connected to the driving gear 5. The driving gear 5 meshes with the driven gear 4. The driven gear 4 is fixedly connected to the outer wall of the mixing tank 8.

[0029] The bearing 13 is provided with a wall scraping mechanism, which includes a slot block 15, an insert block 17 and a "C"-shaped wall scraping plate 18. The insert block 17 is inserted into the slot block 15, and the "C"-shaped wall scraping plate 18 is fixedly connected to one end of the insert block 17.

[0030] Please see Figure 3 The bottom end of the fixed ring 2 is fixedly connected to multiple support legs 1 in a ring array. The inside of the fixed ring 2 is provided with a sliding groove. A sliding ring 3 is slidably connected in the sliding groove of the fixed ring 2. A driven gear 4 is fixedly connected to the top surface of the sliding ring 3. The mixing tank 8 can rotate better by sliding the sliding ring 3 in the sliding groove of the fixed ring 2.

[0031] Please see Figure 4 and Figure 5 One of the support legs 1 is fixedly connected to a motor A positioning block 7, and a motor A6 is vertically mounted on the motor A positioning block 7. The motor A6 is connected to an external power supply. One of the support legs 1 is fixedly connected to a "C"-shaped connecting block 10, and a motor B11 is vertically mounted on the "C"-shaped connecting block 10. The rotating end of the motor B11 is fixedly connected to a stirring rod 12, which is located inside the mixing tank 8. The motor B11 is connected to an external power supply. A bearing 13 is rotatably connected to the outer circumference of the stirring rod 12. A fixing rod 14 is fixedly connected to the outer ring of the bearing 13 and fixedly connected to the bottom end of the motor B11. The inner ring of the bearing 13 rotates while the outer ring does not rotate. The inner ring of the bearing 13 can rotate with the stirring rod 12. The fixing rod 14 fixes the wall scraping mechanism.

[0032] Please see Figure 5 A slot block 15 is fixedly connected to the outer circumference of the bearing 13. A threaded hole A150 is passed through the slot block 15. An insert block 17 is inserted into the slot block 15. A threaded hole B170 is opened on the insert block 17. Nuts 16 are threadedly connected to the threaded holes A150 and B170. In order to make the scraping mechanism removable from the mixing tank 8, the insert block 17 is retracted into the slot block 15 to reduce the lateral length of the scraping mechanism, so that it can be smoothly removed from the feed port 80.

[0033] Please see Figure 1 The mixing tank 8 is equipped with a heating wire inside. The top of the mixing tank 8 is provided with a feed inlet 80 and a discharge outlet 81. The feed inlet 80 is covered with two semi-circular cover plates 9. The heating wire is not shown in the attached drawings of the instruction manual. The heating wire is connected to a power source and is mainly used to heat the inside of the mixing tank 8. The installation of the heating wire on the mixing tank 8 is a conventional and existing technology. Its working principle will not be elaborated here. At the same time, the two semi-circular cover plates 9 cover the feed inlet 80 to seal it and prevent heat loss. At the same time, a solenoid valve is also installed at the bottom of the discharge outlet 81 for opening when discharging material. This valve is also not shown in the attached drawings of the instruction manual.

[0034] The implementation principle of a heating and mixing tank for asphalt production in this application embodiment is as follows:

[0035] Start motors B11 and A6. Motor B11 drives the stirring rod 12 to rotate forward, and motor A6 drives the drive gear 5 to rotate. The drive gear 5 meshes with the driven gear 4 to rotate. The driven gear 4 drives the sliding ring 3 to rotate in the fixed ring 2. At the same time, the sliding ring 3 drives the mixing tank 8 to rotate in reverse, thereby achieving the effect of stirring the asphalt raw materials.

[0036] In the rotating mechanism, the motor A6 drives the drive gear 5 to rotate and mesh with the driven gear 4 to reverse the mixing tank 8. At the same time, the motor B11 drives the stirring rod 12 to rotate forward. Through the internal and external rotation, the asphalt raw materials can be mixed faster, thus improving the mixing efficiency.

[0037] When the stirring rod 12 rotates, the fixing rod 14 positions the scraping mechanism. At this time, the "C"-shaped scraper 18 contacts the inner wall of the mixing tank 8. When the asphalt raw material driven by the rotating mechanism comes into contact with the "C"-shaped scraper 18, it will block the asphalt raw material and make it fall off. This can prevent the asphalt raw material from contacting the inner wall of the mixing tank 8 for a long time and causing it to adhere, thus avoiding the waste of asphalt raw material during feeding and the laborious process of manually removing the raw material from the inner wall of the mixing tank 8.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
